Non-Profit Space Rocket Launching In a Week
Plammox writes "A non-profit suborbital space endeavor lead by Kristian von Bengtson and Peter Madsen is trying to put a man in space. The first test of the boosters and space craft in combination with the sea launch platform will take place this week. The catch? All of this is a non-profit project based on voluntary labor and sponsors. How will they get the launch platform out in the middle of the Baltic sea to perform the test? With the founder's home-built submarine pushing it, of course."

Sven the crash test dummy is in for a wild ride!
The pace at which they've managed to do this work is phenomenal.
How we know is more important than what we know.
I caught this story on Fark, and they linked to a really good thread over on the Something Awful forums with posts directly from these people.
We've made the world's amateur largest space rocket

This is completely awesome, and I wish them the best of luck with the test launch this weekend. :D

They have been running a blog since the beginning on ing.dk (in danish only, unfortunately). Openness is key to the project, that's how they attract the donations that make up all funding.
The astronaut sitting upright is a key part of the design. The spaceship is 60cm in diameter. If he lies down the spaceship needs to be much wider, around 2 metres, and then require a much larger booster rocket.
They aim at a constant acceleration of 4G, which is not very much for a rocket, but this is to make it liveable in the upright position.
Another key part of the design is that it is a hybrid rocket, which has high power, is controllable, and is almost without dangers compared to traditional liquid and solid fuel rockets.
The fuel is actually some rubber substance (not entirely unlike tyre rubber), with liquid oxygen being pumped through to make it burn at high temps. Totally harmless substances, except when you ignite them, produces great thrust, and is even variable, so they can just turn it off if something goes wrong.
Until now they have only been doing static booster tests (all successful). The upcoming launch is the very first flight test. They only aim at going to some 20 km's altitude. The eventual goal is to replace Sven the test dummy with Peter Madsen, and thrust him to above 100 km's - and get him down safely.
